(-x-3y=4) (y=-2+2) use the substitution method please help

there are three prime numbers with only 1 and themselves as factors so i say one is the greatest common factor for all of them.

step-by-step explanation:

ok , let me start from the meaning of word translation .

translation means moving an object by a certain distance in any direction.

the nature of the object i.e shape, size does not change. neither the figure is

reflected, nor rotated.

as δ abc is translated, it is not given it is translated in which direction

so,(2,-7) lies in fourth quadrant.

if translation of t units is applied to the coordinates of b (2,-7) i.e x in right direction,and y in up   then new coordinates, b'=(2+t, -7+t)

if translation of t units is applied to the coordinates of b(2,-7) i.e x in right direction,and y in down   then new coordinates, b'=(2+t, -7-t)

if translation of t units is applied to the coordinates of b(2,-7) i.e x in left direction,and y in up   then new coordinates, b'=(2-t, -7+t)

if translation of t units is applied to the coordinates of b(2,-7) i.e x in left direction,and y in down   then new coordinates, b'=(2-t, -7-t)

$20 bought 16 songs

so:

2 songs would cost 2 * $1.25

3 songs would cost 3 * $1.25

songs would cost x * $1.25

since renata started with $20, then her balance (y) after buying x songs would be:

y = 20 - 1.25*x

well we can use $ left as the y axis and the amount songs purchased as the x axis.   first we are going to divide 20 by 16 to get 1.25 which means that each song is $1.25. *which means after 16 songs on the x axis the lone should be at the bottom at point (0, 0).*   your equation is y=20-1.25x if you need more information just let me know : )
